Title: Improvements relating to tumbler dryers
Inventor: STOREY VICTOR
IPC: D06F58/02
Filed: 1969-07-01
Abstract: 1,241,892. Two-drum tumbler dryers. YORKSHIRE DRYER CO. Ltd. 18 June, 1970 [1 July, 1969], No. 33083/69. Heading F4G. To conserve floor area in launderettes, a tumbler dryer comprises two drying drums 26 disposed one above the other, and independently rotated and supplied with heated air (under the control of coin operating mechanisms located at the front of air heating chambers 11 and 12). Air drawn from the heating chamber 11 (containing a gas burner 24, or steam-heated) by an extraction fan passes through a duct 19 into an upper compartment 13 and out through a duct 20 to an exhaust chamber 16, and air drawn from the similar heating chamber 12 by a further extraction fan passes through a duct 21 into a lower compartment 14 and out through an aperture 22 to an exhaust chamber 15. The extraction fans (not shown) are located in housings 38 and 39 communicating with the exhaust chambers 15 and 16 and with a divided exhaust duct 44, fluff filters 37 being provided in the exhaust chambers 15 and 16. The rear of each drum 26 is carried by a spindle 28 and near the front of each drum is a peripheral band engaged by free rollers 31 and driven rollers 32 rotated via belts 42 by electric motors 41 which also drive via belts 43 the shafts 40 of the extraction fans. Each half of the exhaust duct 44 has a switch operated by a flap in the airstream so as to cut off the supply of gas to the main gas burner 24 if the air speed becomes too small. Electricity and gas supplies are also cut off by switches when the door of a drum 26 is opened and when a door giving access to the filters 37 is opened. Each main gas burner 24 is associated with a pilot burner acting on a thermocouple which cuts off gas supply to the main burner if the temperature of the thermocouple becomes too low. The gas supply is also cut off by a switch if the temperature becomes too high. Each compartment includes a manually-settable thermostat 58.

Title: Method and apparatus for seating a tubeless tyre on a vehicle wheel
IPC: B60C25/12
Filed: 1972-07-14
Abstract: 1402017 Seating tubeless tyre beads ROYAL INDUSTRIES Inc 14 July 1972 [2 Aug 1971] 33158/72 Heading B7C The beads of a tubeless tyre are seated on the rim of a vehicle wheel by securely locating the wheel in a position such that one side of the wheel faces upwardly and the other downwardly loosely disposing the tyre on the wheel rim, and then directing pressurized air into the tyre interior both through the inflation valve on the wheel rim and also upwardly through the gap between the lower tyre bead and the lower part of the rim via a plurality of air outlets exposed to the atmosphere and located at positions circumferentially spaced around the gap. The air may be directed upwardly towards the rotational axis of the wheel at an angle of 40 degrees thereto and may enter the gap over an arc which does not exceed 300 degrees in extent. In one embodiment, Fig. 1, the wheel is secured on a horizontal platform 11 by means of jaws 12, 13, 14 attached to the outer ends of levers 15, 16, 17 connected at their inner ends to a plate which may be rotated around a vertical shaft 24 to move the jaws into engagement with the radially inner periphery of the lower part of the wheel rim, and air is directed into the gap from orifices 19, 21, 23 in members 18, 20, 22 mounted on the outer ends of the levers 15, 16, 17, an air source being connected through a foot-operated valve (27) (Fig. 2, not shown) both to the members 18, 20, 22 and to the tyre inflation valve. In an alternative embodiment, Fig. 5, the wheel is secured to an inclined platform 31 by means of a pair of spaced jaws 33, 34 fixed to the platform and a jaw 35 movable towards and away from the jaws 33, 34, the jaw 35 having coupled for movement therewith a shaft 36 extending perpendicularly from the platform and a plate 37 carrying arcuate tubular members 38, 39 with orifices 47, 48 for directing air into the gap, a pneumatic control system being provided both to move the jaw 35 and to supply air to the orifices 47, 48 and the tyre inflation valve, which system is constructed such that air cannot be supplied to the orifices and the inflation valve until the jaw 35 has been moved to secure the wheel on the platform. Reference has been directed by the Comptroller to Specification 1,315,780.

Abstract: 1,154,644. Ceramic thoria. UNITED STATES ATOMIC ENERGY COMMISSION. 20 July, 1967 [30 Sept., 1966], No. 33318/67. Heading C1A. A ceramic thoria product is made by mixing powdered thoria with an aqueous solution containing sufficient inorganic anions to form a colloidal dispersion and then, after evaporation, a coagulated settleable precipitate, dewatering the precipitate to a plastic consistency, wetforming into a desired configuration, substantially drying and sintering. Preferably, steam denitrated thoria powder containing 0-03 mol. N0 3  per mol. thoria is added to nitric acid, containing 0À1-0À18 mol. N0 3  per mol. thoria, at 95-100‹ C. and stirred to give, after evaporation for 4 hours, a precipitate of colloidal thoria coagulates whose water content is reduced in a heated atmosphere to 15-23 wt. per cent. The residual mass is extruded, e.g. to a rod-shaped configuration (for use in nuclear fuel elements), dried to 1 wt. per cent water content, and sintered in a furnace by raising the temperature to 1200‹ C. in steps of 50- 100‹ C/hr. up to 600‹ C. and 100‹ C/hr. thereafter, and maintaining at 1200‹ C. for 1 hour. The final density is 97-99‹ of theoretical. Presintered thoria powder and/or thoria powder lightly calcined at 200-500‹ C. may be incorporated in amount up to 60 wt. per cent into the plastic mass prior to extrusion, providing products of density 70-98% of theoretical. Products containing up to 5 wt per cent uranium (based on U-Th content) may be prepared by substituting uranyl nitrate for a portion of the nitric acid. Other specified inorganic anions are bromide, fluoride, chloride, sulphate and phosphate.

Title: Improvements in or relating to suction cleaners
IPC: A47L9/19
Filed: 1960-09-28
Abstract: 905,474. Suction cleaner filters. SIEMENSELECTROGERATE A.G. Sept. 28, 1960 [Sept. 30, 1959], No. 33371/60. Class 8(2). A device for indicating when the filter of a suction cleaner is blocked consists of a ball 9, free to move vertically inside vertical tube 8, through which tube a small proportion of the clean air passes. Under normal operation the flow of air through the tube is sufficient to force the ball to the top of the tube, where it is visible to the operator. When the filter is blocked and the air flow is reduced, the ball falls and is no longer visible. The ball may be replaced by a piston from which extends a pin, the pin being visible only when the filter is not blocked. The piston may be restrained by a coil spring.
